SuperFish – removal tool

SuperFish is an adware that tampers with your computer’s encryption certificates, which seemingly leaves your otherwise “encrypted” communications insecure whenever you are on a shared WiFi connection (like at a coffee shop). It can silently intercept and decrypt HTTPS connections, tamper with pages and inject advertisements.

Superfish is present on Lenovo laptops sold between September 2014 and January 2015, although the company says no Thinkpads were shipped with the Superfish malware. Still, you can check your Lenovo computers for this nasty software with the help of a test created by researcher Filippo Valsorda.
